CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 609,858, dated'August 30, 1898. Application filed October 19, 1897. Serial No. 655,706: (No modem T at whom it may concern.-

Be it known that I, EDWARD B. WEST, a citizen of the United States, residing at Bet tie, in the county of Upshur and State of Texas, have invented a new and useful Churn- Dasher, of which the following is a specification.

My invention relates to churn-dashers, and has for its object to provide a simple, corn pact, and eflicient construction and arrangement of parts whereby the maximum agitation of the contents of a churn receptac1e may be attained Without causing the splashing thereof, and to provide means for facilitating the cleansing of the dasher-blades.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed'out in the appended claims.

In the drawings, Figure l is a view of a churn, with the churn-receptaclein section, showing a dasher constructed in accordance with my invention. Fig. 2 is a sectional View of the dasher-operating mechanism and the contiguous portion of the dasher. Fig. 3 is a detail view of one of the dasher-blades detached. Fig. 4.- is a detail sectional view to show the means whereby the auxiliary dasherblade is detachably secured to the tubular.

dasher-spindle.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlngs.

1 designates a bracket consisting of a casting having a hollow or channeled body portion 2 and an integral clamp 3, of which one of the jaws is fitted with a set-screw 4. Said hollow body portion terminates in upper and lower bearings 5 and 6, in which is mounted a dasher-spindle 8, carrying fixed and loose pinions 9 and 10, the former being preferably keyed or secured by means of a pin 11 to the spindle, while the latter is held in place by means of a collar 12, also keyed or secured by a pin 13. Rotary motion in opposite directions is communicated to said pinions by means of a driving or master gear 14, having an operating handle or grip 15. The drivinggear is mounted upon a stub-shaft 16, which is fixed to a boss 17, bridging the open side of the hollow body portion of the bracket.

The main dasher-blade consists of a stem 18,

provided with radially-disposed wings or paddles 19, and the upper extremity of the stem is detachably secured by an interlocking joint with the main dasher-spindle. In the construction illustrated the main dasher-stem is provided with a threaded projection 18 to engage a left-threaded socket in the dasherspindle.

The auxiliary dasher-blade consists of a plurality of oppositely-extending loops 20, having their sides spaced to allow the main dasher-wings to pass therebetween and havinga stem, 21, terminating at its upper extremity in an eye 22, engaged by a thumbscrew 23, engaging a suitable socket in the tubular auxiliary dasher-spindle which consists of the hub of the pinion 10. In the construction illustrated the auxiliary dasherblade is constructed of a single blank of heavy Wire or rod doubled upon itself repeatedly to form the several looped wings 20, terminating at one end in a bearing 24 for the reception of the lower extremity of the main dasherstem andextending at its upper end to form the auxiliary dasher-stem 21.- The sides of the looped auxiliary dasher-wings are offset, as shown at to receive the main dasherstem, whereby the body portions of the main and auxiliary dasher-win gs are adapted to lie in a common plane, while the auxiliary dasherstem is curved rearwardly to engage the opposite side of the main dasher-stem, whereby all tendency of the auxiliary dasher to vibrate laterally is overcome, and the dasher-blades,

while readily detachable, by loosening said thumb-screw and deflecting the auxiliary dasher-stem sufficiently to disengage it from the main dasher-stem, are caused to rotate coaxially.

' It will be understood that the detachability of the dasher-blades provides for their being cleansed with facility, while the thin wings, which are employed as the beaters, provide for the agitation of the contents of a churnreoeptacle without the splashing incident to the use of flat blades. The wings of both the main and auxiliary dashers are preferably constructed of heavy wire, those of the main dasher-blade' being straight and radially disposed, While' those of the auxiliary dasherblade are looped and are also radially disposed with relation to the main dasher-stem.

Various changes in the form, proportion,

and the minor details of construction maybe resorted to without departing from the spirit claim is 1. Achurn-dasher having coaxial main and auxiliary dasher-blades, the main dasherblade consisting of a stem' having radiallydisposed wings, below the lowermost of which the stem projects to form a terminally free extension, and the auxiliary dasher-blade consisting of a series of wings, which operate in transverse planes between those of the main dasher-wings, the auxiliary dasherblade being mounted. at its lower end upon said extension of the main dasher-blade for downward displacement, and being spirally extended at its upper end around, and yieldingly engaged with, the main dasher-stem, to provide for lateral displacement, whereby when the upper end of the auxiliary'dasherblade is disengaged, the lower end thereof may be dismounted downwardly from the gnain stem extension, substantially as speci- 2. A churn-dasher having a main dasherblade comprising a stem and a series of radially-disposed wings, and an auxiliary dasherblade comprising a series of looped wings, having their sides arranged respectively above and below the planes of the main dasher-wings, the sides of each of'the auxiliary wings having alined half-bearings'to receive the stem of the main dasher-blade, respectively between the planes of the main dasher-wings, and said auxiliary dasher also having a lower terminal bearing in which the extremity of the main dasher-stem is removably seated, and an extension or stem which is in bearing contact with the main dasherstem at the opposite side from said half-bearings, to maintain the latter in operative relation with the main dasher-stem, substantially as specified;

3. The combination with a main dasherblade having a revoluble stem and radiallydisposed wings, of an auxiliary dasher-blade constructed of a single blank of wire,'doubled upon itself successively to form a plurality of oppositely-extending loops, of which the sides are arranged transversely opposite the intervals between the main dasher-wings, and are offset laterally in a common direction to form half-bearings to bear against the main dasher-stem at one side, said blank being proiliary dasher-blade upon the main dashervided at its extremities with extensions which bear against the opposite side of the main dasher-stem from said half-bearings,and combining therewith to revolubly mount the auxstem, and means for communicating rotary motion in opposite directions to the main and auxiliary dasher blades, substantially as specified,

4:. A churn-dasher having a main dasherblade comprising a stem and a plurality of radially-disposed straight wings or beaters, below the lowermost of which the stem projects to form a terminally free extension, and an auxiliary dasher-blade, constructed of a single blank of wire and having wings consisting of a series of oppositely-disposed openended loops, with their open ends disposed alternately in opposite directions, and between the sides of which the main dasherblade wings operate, said auxiliary dasherblade terminating at its lower end in a bearing-eye mounted upon said lower extremity of the main dasher-stem, and terminating at its upper end in a stem which is coiled spirally around and yieldingly engages the stem of the main dasher-blade to form an upper bearing, whereby the lateral displacement of the spirally-coiled upper end of the auxiliary blade provides for the downward dismounting of the bearing-eye at the lower end thereof from the main stem extension, substantially as specified.

5. The combination of concentric main and auxiliary dasher spindles, a main dasherblade having a stem provided with a series of radial dasher wings or heaters, and having a detachable interlocking connection with the main dasher-spindle, an auxiliary dasherblade detachably mounted upon the main dasher-stem and comprising a series of oppositely-disposed' loops arranged radially with relation to the main dasher-stem, and extended to form a stem, and a securing-screw for attaching the stem of the auxiliary dasherblade to the auxiliary dasher-spindle, substantially as specified.

6. The combination with concentric main and auxiliary dasher-spindles, of main and auxiliary dasher-blades detachably secured respectively to said main and auxiliary dasher-spindles, the main dasher-blade having a stem provided with a series of radially-disposed wings or boaters, and the auxiliary dasher-blade comprising a plurality of oppositely-disposed loops having their sides spaced apart to receive the main dasher-blade wings or heaters, having their sides offset laterally in one direction to form half-bearings to receive the main dasher-blade stem at one side and arrange the body portions of said loops radially with relation to the main dasherblade stem, terminating at its lower end in a bearing in which is stepped the lower end of the main dasher-blade stem, and terminating at its upper end in a stem which is detachably coiled around the main dasher-blade stem to bear against the opposite side thereof from said offset portions of the looped wings, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

EDWARD B. WEST.
